12-4-5 Origin Search Operations
 Operating Mode 1 (with Error Counter Reset Output, without Positioning
Completed Input)
Connect the phase-Z signal from the Servo Drive to the Origin Input Signal.
When the Origin Input Signal is received, the pulse output will be stopped and the Error Counter
Reset Signal will be output for about 20 to 30 ms.
Though the Origin Proximity Input Signal is received, the signal will be ignored and the motor will
begin decelerating from the origin search high speed to the origin search proximity speed. In this
operating mode, the motor will stop at the Origin Input Signal after deceleration is completed.
Operating Mode 1 with Origin Proximity Input Signal Reverse (Origin
Detection Method Setting = 0)
The Origin Input Signal can be detected immediately after the Origin Proximity Input Signal turns
OFF if the deceleration time is short, e.g., when starting from within the Origin Proximity Input Sig-
nal. Set an Origin Proximity Input Signal dog setting that is long enough (longer than the decelera-
tion time.)
